Analyse et suivi du phénomène de la désertification en Algérie du nord

The present study aims to work out a methodology based on the use of the sensors such TERRA MODIS (MODerate resolution Imaging Spectroradiometer) in the desertification following and the detection of desertification risk zones in the northern area of Algeria. To this end, some geophysical paramete...
